Rewilding

Rewilding is a conservation ethos that is gaining in popularity worldwide. Well established now in North America and Europe, rewilding in Australia is still a relatively new concept.

What’s NPA doing in this space?

NPA is a partner on an exciting project called “nature-based solutions for growing cities: rewilding policies and practice”. Led by the University of Sydney, the project will develop urban rewilding case studies to demonstrate how rewilding can deliver social and economic benefits to urban areas.The project will focus on bandicoots in Sydney’s inner west; powerful owl movements throughout Sydney and bringing native pollinators back to urban green space. This project builds on NPA’s strong citizen science programs, and the outcomes will help embed rewilding principles into policy to benefit both people and wildlife.

Rewilding is applicable at multiple scales and in both rural and urban settings

Rewilding in Australia requires a shared vision in order to progress and meet its potential

Rewilding efforts should include a research component in order to demonstrate proof of concept and positive ecological change

Rewilding efforts will require policy changes from government

Rewilding FAQs

Q: I thought rewilding was just about predators, isn’t this the case?

A. Not necessarily. Predators are an important consideration, and in some rewilding efforts the primary consideration. But because rewilding is a focus on ecosystem processes and function, anything that increases ecological function can be considered rewilding. For example, this could include restoring natural flood regimes; removing fences in a landscape to allow animals to move more easily; allowing forests to recover from logging to speed hollow formation or reintroducing animals that perform important ecological roles like digging and seed dispersal. Emus are an example of an animal very important in seed dispersal, and that’s why we’ve used emus as our rewilding image.

Q: I have heard about rewilding projects that use fences. How can fences be considered rewilding?

A. Australia is a unique case in this regard! Because so many of Australia’s small mammals (particularly in the arid zone) are threatened by introduced foxes and cats, fenced enclosures are used to keep these predators out and allow the native mammals to recover. The Australian Wildlife Conservancy and Arid Recovery are very successful in this approach. However, the rewilding forum identified fences as a stepping stone to broader landscape rewilding, not an end point in themselves, because fences are ultimately not consistent with the goal of promoting self-sustaining ecosystems.

Q: How can rewilding be relevant to cities?

A. Because the restoration of ecological function can be applied to urban parks, gardens and bushland. For example, reintroducing or encouraging native bees to gardens will help pollination of plants, while encouraging bandicoots into gardens will improve soil formation via their digging. These examples are consistent with the rewilding focus on ecosystem processes and function.

Q: Why are people relevant to rewilding? Aren’t people the biggest threat to nature?

A. Like it or not, human populations exert a huge influence on the distribution and abundance of other animals. We’re the ultimate ecosystem engineers. Although this influence can be negative, it isn’t always (think of a gardener in the inner city that plants native shrubs to encourage native birds, or the restoration of urban floodways to provide wildlife habitat). By recognising the influence of humans on nature, rewilding efforts can try to improve how human populations interact with wildlife and, ultimately, improve biodiversity. That’s why rewilding is not synonymous with the concept of wilderness (a large area of natural habitat largely free of human influence).

Q: So why do you promote National Parks and wilderness then?

A. National Parks are the best tool we have in the world for protecting species. Habitat destruction by humans is the number one factor that is driving species declines worldwide, and National Parks prevent habitat loss. Rewilding is a complementary tool for conservation, not a replacement for National Parks and wilderness.

Help NPA stand up for nature

Nature needs our help more than ever.The fires of 2019/2020 have left a permanent imprint on many of our natural landscapes and pushed once safe species towards extinction. Against this backdrop, climate change, destructive development, logging and loss of marine conservation are posing increased threats to nature.

Your support will help NPA retain and build the resources we need to face the challenges ahead with hope. And it will enable us to participate in a process that influences crucial policies and decisions that will have a permanent impact on our national parks and natural landscapes.
